Sweet & Fortified Wines Flashcards
Which region is the center of Sherry production?
Andalucía, Spain (in Jerez)
Name the 3 towns where Sherry must be matured
Jérez de la Frontera
Sanlúcar de Barrameda
El Puerto de Santa María
What’s Jerez’s climate and how does it affect wine?
Hot sunny mediterranean climate
Vineyards near the coast benefit from the cooling of the westerly humid wind “poniente”.
Vineyards can be damaged by the “levante” which blows from the east.
What’s the poniente?
It’s a cool humid westerly wind benefiting the vineyards in Jerez
What’s the levante?
It is a hot wind blowing from the east in Jerez, which can damage vineyards.
What soil is typical from Jerez?
Albariza, which has high chalk content and provides good drainage but also retention of water.
What are the main grapes involved in the production of Sherry?
Palomino
Pedro Ximenez (PX)
Muscat de Alexandria
Grape representing the majority of vineyards in Jerez
Palomino
Where is Pedro Ximenez (PX) grown?
Montilla-Moriles (grapes are brought to Jerez)
Name of the thin-skinned, ideal to be sun-dried grape used to produce Sherry?
Pedro Ximenez (PX)
Main grape used to produce dry white Sherry
Palomino
Type of ageing for Sherry that does not require the development of Flor
Oxidative ageing
Type of ageing for Sherry that requires the development of Flor
Biological ageing
Steps to produce dry Sherry wines
- Destem and crush
- Press
- Alcoholic Fermentation–> It happens in steel vats at 20-25C to produce neutral base wine with 11-12% ABV.
- Classification as either biological (typically those lighter/paler/finesse) or oxidative ageing (typically those darker/richer)
- Fortification (15-15.5% abv for biological and 17% abv for oxidative)
- Sobretabla
- Incorporation into the Solera system
- Flirtation and bottling
At what temperature does the alcoholic fermentation of Sherry happens?
20-25 C
% ABV in the neutral base wine in the process of making Sherry
11-12%
What’s biological ageing
A process to age Sherry which requires the presence of Flor
What’s the Flor?
It is a thick layer of yeast strains on the surface of Sherry wine, which feed off the alcohol, nutrients and oxygen to produce carbon dioxide and acetaldehyde, which is what gives biologically aged sherrys their unique flavor. The flor also protects the wine from oxidation.
At what % ABV the Flor dies?
15.5% ABV
What is sobretabla in the making of Sherry?
It refers to the fortified base wine that is sent aside for a few months before incorporating it in the solera system
Why is sobretabla important to biological aged Sherries?
Biological ageing requires the development of Flor. Winemakers need to constantly checked if Flor is well developed during sobretabla for it to pass on to the solera system.
What happens to the wine if Flor does not develop properly during sobretabla?
It is either rejected or re-fortified to 17% ABV and send to oxidative ageing.
Sobretabla is NOT that important for what kind of ageing in Sherry?
For oxidative ageing. This process does not require the development of Flor.
Sherry has to be aged in what kind of barrels?
600 liters butts
What techniques do winemakers put in place to ensure the development of Flor?
Keep on incorporating young wine in the solera system to ensure Flor has enough nutrients
Ensure Flor is exposed to oxygen (filling the butts only 5/6ths)
Keeping a cool, humid environment in the bodegas
What’s the solera system?
Sherry’s maturation process. Wine flows from different levels according to their age (criaderas) so young wine get the character of older wine. As you extract older wine, you replenish the same volume with wine from a younger criadera and so on.
What are the benefits of the solera sytem?
Ensures consistency of the wine when producing Sherry
How many criaderas can a solera system have?
as many as 14
What’s a criadera?
A series of butts organised in different levels according to their ages in the solera system for Sherry
What does Flor generates during biological ageing?
Carbon dioxide and acetaldehyde.
Acetaldehyde is what gives biological aged sherries their flavour
What kind of temperature does Flor favor?
Cool moderate temperature.
Describe the process to produce Sweet Sherry wines
- Grapes picked and sun-dried.
- Press
- Alcoholic fermentation. Since yeast struggles fermenting all the concentrated sugar in these grapes, the alcohol content is quite low and once the fermentation stops, the wine needs to be fortified to 17% ABV
- Wine is aged oxidatively
- Wine incorporated into the solera system.
List the different Sherry styles
- Fino / Manzanilla
- Oloroso
- Amontillado
- Palo Cortado
- Pedro Ximenez
- Muscat
- Pale Cream
- Medium
- Cream
List the types of Sherry that undergo biological ageing
- Fino / Manzanilla
- Amontillado (initially)
- Medium (initially)
- Pale Cream
Fino that can only be matured in Sanlúcar de Barrameda
Manzanilla de Sanlúcar de Barrameda DO / manzanilla Fina
Ageing process for Fino / Manzanilla
Biological
Notes for Fino / Manzanilla
Characteristic Tangy / Salty
Pale lemon
Aromas of citrus fruit, almonds and herbs
Bready notes (coming from Flor)
Does Fino improves with bottle ageing?
No - it needs to be consumed as fresh as possible
Ageing process for Oloroso
Oxidative
Notes of Oloroso
Brown in color, full bodied
Toffee, leather, spice and walnut
Very old olorosos are very concentrated
What’s Amontillado?
A style of Sherry that undergoes both biological and oxidative ageing.
Notes of Amontillado
Amber/Brown
Combines yeast aromas with oxidative ones.
A rare Sherry that combines the characteristics of 2 other styles?
Palo Cortado
Palo Cortado is difficult to distinguish from these 2 styles
Amontillado and Oloroso.
Mention the natural sweetened and sweetened styles of Sherry
Naturally Sweet–> Pedro Ximenez and Muscat
Sweetened –> Pale Cream, Medium and Cream
